Defining Normal Vertebral End Plates Cobb Angle from T12 to L4 Using Computerized Tomography in Sudanese Populations

Abstract

Abstract:The aim of this study is to establish normal values as reference for vertebral end plate from T12 to L4 in normal Sudanese subjects using computerized tomography (CT).130 lateral scout CT scans done using GE Healthcare machine with KV120, MA10-50 for lumber vertebra were obtained from subjects (65 males and 65 females) their ages ranged from (15-74) years old .Endplates angle from T12 to L4 were measured using Cobb Method for both genders and the data were correlated to their ages. For males the endplates mean angles were found to be 7.4±3.5,6.6±3.3,4.7±2.9,5.3±3.8,18.8±7.6 and for females 9.2±4.5,9.9±4.5,9.7±4.2,6.8±4.3,5.9,4.6 for T12,L1,L2,L3and L4 respectively. The research also studied the difference according to gender; it showed significant difference at p value 0.05, the end plates angles were affected as the subjects ages increase. The study concluded that the mean Cobb angle end plate differs significantly from males and females Sudanese subjects and it has relation with age and the values differs from what was mentioned in the previous studies, the knowledge of the normal end plates angle allows better characterization and diagnosis for vertebra from T12 to L4.

Evaluation of Lumbar Spine Morphology in Magnetic Resonance Images Using Cobb's Method

“…Mode 1 and total spine curvature were found to be significantly correlated ( R = 0.97, P = .001), as were mode 2 and mean absolute deviation of segment curvature ( R = 0.80, P = .001) 18 . The understanding that usual endplate inclination enables more accurate diagnosis and care for vertebrae from T12 to L4, because the mean Cobb angle endplate varies substantially between male and female Sudanese patients and has a link to age, and its values differ from those indicated in an earlier research 19 …”

“…18 The understanding that usual endplate inclination enables more accurate diagnosis and care for vertebrae from T12 to L4, because the mean Cobb angle endplate varies substantially between male and female Sudanese patients and has a link to age, and its values differ from those indicated in an earlier research. 19 For the spinal segments L2, L3, L4, and L5, the results demonstrate a direct linear relationship between Cobb angle and intervertebral discs spacing, with the angle rising by 0.46, 0.80, 1.05, and 0.82 degrees per millimeter of cervical disc gap, respectively (Figures 15-18). Vertebral bodies displayed increasing lordotic bend with kyphotic bend in L1, a tendency to neural bend in L2, and a statistically Feature Article significant variance between observations.…”
